COOKING-STOVE.

Specification of Letters Patent No. 2,216, dated August 11, 1841.

To all whom it may concern Be it known that I, SAMUEL L. CHASE, ofoodstock, in the county of Windsor and State of Vermont, have inventedcertain Imprm ements in the Manner of Constructing a Stove for Cooking;and I do hereby declare that the following is a full and exactdescription thereof.

In the accompanying drawing Figure 1, is a perspective view of myimproved stove, and Fig. 2, a vertical sect-ion thereof through, andalong, the middles of the ovens.

In this stove I use the swinging hearths A, A, divided into two parts,and con structed, generally, in the same manner as the swinging hearthdescribed in the specificat-ion of Letters Patent for a cooking stovegranted to me under date of the 25th day of September 1840. The doors B,B, opening into the fire chamber, do not when closed extend to thebottom of said opening, but leave a draft space below, which when theparts A, A, of the swinging hearth are closed, is in part covered by theprojecting pieces a, a, on said hearth, but not entirely so, there beingstill a small draft space beneath the pieces a, a, for the escape ofsmoke and fumes from the sunk hearth O, C, when the swinging hearth isclosed. The sunk hearth is furnished with grate bars Z), 6, having aspace beneath them for the reception of live coals; and there is a drafthole at each end of the sunk hearth, below said bars, as shown at c,which may be stopped at pleasure. The space under the grate bars Z), Z),is divided into two compartments, by a partition immediately below thatmarked (Z, and the end of which is shown by dotted lines at 6. By meansof this partition one half only of the space underthe bars Z), Z), maybe used, the draft hole under the other half being closed There are twoovens D, D, above and behind the fire chamber, the doors of which areseen at E, E. The flue space by which these ovens are to be heated passabove, between, and below them, without the intervention of anypartition, or valve, as shown at F, F, in Fig. 2; and these are theironly flue spaces. Into these flue spaces there are four openings throughthe plate G, G, which is the back plate of the fire chamber. Three ofthese openings, f, g, and it, lead into the flue between the two ovens,and into the vertical flue spaces, as shown by the dotted lines at f, g,72, in Fig. 2; and the fourth, 5, leads into the lower flue, under thelower oven, as shown by the dotted lines 2', in Fig. 2. \Vhen anthraciteis to be used as fuel, a grate must be inserted in the fire chamber, andthe stove must be so constructed as that the opening 2', shall beelevated above this grate; the back portion of the stove containing theovens and flues must also be elevated above the bottom of the firechamber, to such height as to bring the respective openings through theplate G, G, to range with the flue spaces into which they are to open.The openings f, and Zr, are to be furnished with dampers, the handle ofone of which is shown at 7'. There may, also, be a damper to the opening2', if preferred.

From the foregoing description the direction of the draft will bereadily understood. That portion which passes direct from the tirethrough 2', will divide off toward each of the end flues, ascend throughthem and pass along the upper flue to the eXit pipe H. That portionwhich enters through g, above the tire will, in like manner, divide offtoward the two ends, and the smoke and heated air will unite in the endflues with that which passed through 2'. Vhen it is desired that theheat in the center flue should be lessened, the dampers closing 7, andmay be opened, and the desired effect will be produced.

Having thus, fully described the manner in which I construct my improvedcooking stove, and explained the use and operation of the respectiveparts thereof; what I claim therein as my invention, and desire tosecure by Letters Patent, is

1. The dividing the sunk hearth into two compartments, below the gratebars Z), Z), in combination with a stove having a swinging hearth, and adraft space below the projections (4, a, on said swinging hearth, in themanner, and for the purpose, above described.

2. I also claim the manner in which I have arranged and combined theflues, and the four spaces, or openings, leading into them from the firechamber; the whole being constructed, governed, and operating as setforth.
